The outer surface of the second liquid outlet pipe 17 is fixedly connected with a UV detector 21, a conductivity detector 22 and a PH detector 23. When the liquid passes through the second liquid outlet pipe 17, it flows through the UV detector 21, the conductivity detector 22 and the PH detector 23 respectively, which is convenient for detecting the liquid. After the detection is completed, the liquid is discharged through the second liquid outlet pipe 17.

[0038] The working principle of this embodiment is as follows:

[0039] The system pump 2 extracts the liquid and transports it to the first four-way valve 4 through the pressure flow cell 3. The liquid is transported to the bubble trap 7 through the first four-way valve 4. The bubble trap 7 removes the bubbles in the liquid and then transports it to the second four-way valve 5 through the first four-way valve 4 again, and is transported to the first liquid outlet pipe 16 through the second four-way valve 5. The first liquid outlet pipe 16 and the liquid inlet pipe 15 are externally connected to the chromatography column. After chromatography by the chromatography column, it enters the second four-way valve 5 again through the liquid inlet pipe 15 and enters the inside of the second liquid outlet pipe 17 through the second four-way valve 5. When the liquid passes through the second liquid outlet pipe 17, it flows through the UV detector 21, the conductivity detector 22 and the PH detector 23 respectively, which is convenient for detecting the liquid.
